Specification of Letters Patent.

Application filed May 7, 1910. Serial No. 559,867.

Patented May 30, 1911.

, My invention consists in the combination ciently free from water as tobe soluble in of an oil or similar vehicle, an emulsifying agent such asa' Water-soluble soap suffithe oil and an oil-soluble compound of copperor other metal, having a substantial scale removing and lnsecticidalaction.

As a basis for a, miscible oil, I prefer to use such oil bases askerosene, hea or light petroleum oils, residual or asp alt oils, crudeoils, rosin oils and spirits, or vegetable oils such as corn and cottonseed with their foots, residues and distillates, fish, menhaden, porgy,cod and other fish oils or animal oils such as lard, tallow and horseoils,

tankag'e grease, wool grease and degras ref- I use oils extracted fromleather, etc., and solvent resins such as the resin obtained fromguayule rubber and other resinous bodies.

As a 'basis for the saponifiable'qpody, I may use ordinary rosin andsimilar resins, 'oleic and stearic acid, 'sulfonated oil, wool grease,fish oils as menhaden oil or other saponifiable stock, but preferably Imake use of ordinary rosin or a mixture of rosin and red oil orcommercial oleio acid.

'ably use cresy If it becomes desirable to use a blending material of ahenolic character, I preferiic acid for this purpose although creosoteobtained from coal tar or other tar, and similar carbolic material maybe employed. The metal base used as the insecticidal body in the form ofa metalloorganic compound is preferably co per, lead, zinc, antimon orarsenic. As a asis for the soap, I pre er to make use of potash as thesaponifymg alkali althou h soda or other alkaline agent may be us inwhole or in part. The potash soaps, particularly those of rosin andoleic acid, 1f largel freed from water, are readil soluble un er theaction of heat in most 0 the oils above mentioned. This is especiallythe case if creosoteor-similar-bleinding agent is present.

With kerosene-and the heavy petroleum oils,

some difficulty obtains in the dissolution in oil of these concentratedwater-soluble soaps unless a little creosote or cresylic acid is presentand 'for that reason, I prefer to use a blending agent of the characterdescribed,

In order to produce miscibility, that is to say, to make the oil capableof either dis solving in water to form a clear transparent solution orto form one which readily emuL. sifies with water and may be dilutedindefi nitely without any material separation of I the emulsifiedparticles, a substantial proortion of such water-soluble bodies must ecarried by the oil.

The metallo-organio compound of a waterinsoluble character preferably issecured by making soap from among the metals mom tioned, as for example,copper soap may be made by precipitating sodlum oleate'with coppersulfate, of by heating copper carbon ate or hydroxid with red oil oroleic acid i to a temperature of about 200 C. for an hour or moremetallo-organic oil-soluble compounds are produced. For example, twoparts of red oil one part of guayule resin and one part of nel powderedcarbonate of copper are heate to a temperature of 140 to 180 C. with theresult that the carbonate dissolves to a very large extent forming acopper soap containing copper oleate and copper guayulate or some corn.-bination of copper with guayule resin. This metallo-organlc compound ofcopper, dlssolves very readily in oils and should be added to the oilbasis used in makin the miscible oil. Preferably, the metal o-organiccompound as specified is made and this is introduced. with rosin andole1c aold into a kettle. Heat is applied and the mmture melted.Kerosene, heavy petroleum or other oil preferably-together with some,

when it'forms an emulsion of an exceednicely pm.

ingly-permanent character. Bly

portioning the amounts of oi and copper soap, a mixture may bemade, the011 portion of which has theprecise speclfic gravity of water or ofdilute soap so utionso that the emulsified particles W111 remain'msugPeriod after. thins-y pension for an indefinite tion to workingstrength.

A specific formula herein given by the way of illustration is as follows:20 pounds each of rosin and red oil are melted in a kettle and to thisis added 50 pounds each of guayule resin, cresylic acid and keroseneoil. 80 pounds of copper oleate and guayulate base above mentioned areintroduced and then approximately 13 pounds of a solution of causticpotash, of a specific gravity of 1.47 are added and the mixture heatedand stirred until the incorporation is complete. A greenish coloredmixture is thus produced which when mixed with a large amount of waterforms a relatively permanent bluish green emulsion. As the copper isactually dissolved in the oil particles of the emulsion, there is notthe danger in its' application that obtains with Bordeaux mixture andthe like. For example, when the emulsion is sprayed on fruit trees, thecopper does not act in a corrosive manner and cause defoliation.

Variations of the above illustrative for mula may be made in accordancewith the character of the mixture desired for any particularapplication, as .for example, the guayule resin and cresylic acid may besubstituted by rosin oil and petroleum oil or the proportions varied inother ways. The amount of copper compound or. other metallic base to beadded depends on the strength required and the degree of emulsification.

For sprays, the'cresylic acid may be omitted entirely when the metallicbase is readily soluble in the oil base used.

It will be noted that the formulas above set forth include a verysubstantial pei'centage of soap, as well as the oilsoluble coppercompound itself, which imparts tothe comof copper sulfate, which wouldnot. prop erly attain the object of the present invention, namely theroduction of an oil of satisfactory miscibi it due to .the presence of asubstantial percentage of soap, at least 5%and preferably from 10% to20%, and likewise a substantial proportion of an oil- I solublecopper-compound, preferably 8% to 10%. The foregoing formulas aretherefore proportioned so as to provide an amount 'of soap adequate torender the copper-laden oil properly miscible. f J

A miscible oil comprising a substantiallywater-insoluble oleaginous base, a Water-insoluble metallo-organiccompound soluble in said oleaginous base and an aqueous soap solutionsoluble in said oleaginous base.

2. A miscible oil comprising a substantially water-insoluble mixture ofoleaginous material, a water-insoluble metallo-organic compound solublein said oleaginous material and'a concentrated aqueous solution of soapmisciblewith said oleaginous material.
